An international research team reports the discovery of Homo sapiens fossils from the cave site Ilsenhöhle in Ranis, Germany. Directly dated to approximately 45,000 years ago, these fossils are associated with elongated stone points partly shaped on both sides (known as partial bifacial blade points), which are characteristic of the Lincombian-Ranisian-Jerzmanowician (LRJ).
The inner ear of a 6-million-year-old fossil ape reveals clues about the evolution of human movement.
Small omnivorous and insectivorous dinosaurs may have flapped small, feathered primitive wings to scare prey out of hiding places, according to a study published in Scientific Reports.
An international team of researchers from McMaster University, University of Alaska Fairbanks and the University of Ottawa has tracked and documented the movements and genetic connections of a female woolly mammoth that roamed the earth more than 14,000 years ago.
Scientists study developing lamprey embryos to clarify the origin of vertebrate head, paving the way to a better understanding of ancestral vertebrates.
Researchers at the University of Liège (ULiège) have identified microstructures in fossil cells that are 1.75 billion years old. These structures, called thylakoid membranes, are the oldest ever discovered.
Significant evolutionary changes happen gradually as opposed to in dramatic ‘monster’ steps, biologists have discovered, answering the long-debated question as to how game-changing innovations like flight, vision, and the bearing of live offspring came to be.
The egg did come first. Egg-laying arose deep in evolutionary time, long before animals even made their way onto land.
A groundbreaking study has found that evolution is not as unpredictable as previously thought, which could allow scientists to explore which genes could be useful to tackle real-world issues such as antibiotic resistance, disease and climate change.
Primates – and this includes humans – are thought of as highly social animals.
Central features of human evolution may stop our species from resolving global environmental problems like climate change, says a new study led by the University of Maine.
In general, frogs’ teeth aren’t anything to write home about—they look like pointy little pinpricks lining the upper jaw.
Natural selection acts on phenotypes constructed over development, which raises the question of how development affects evolution.
Horses have developed long faces simply ‘because they can,’ a team of evolutionary biologists say.
تقوم أجسامنا كل يوم ببعض الأمور الغريبة وغير المعتادة. فيما يلي بعض الأسئلة والأجوبة التي تقدم التفسير العلمي وراء حدوث ذلك.
A diario, el cuerpo hace algunas cosas bastante extrañas e inusuales. A continuación, se incluyen algunas preguntas y respuestas que ofrecen la explicación científica de por qué suceden.
Todos os dias, nossos organismos reagem de formas peculiares e incomuns. Aqui estão algumas perguntas e respostas que explicam a base científica desses eventos.
Paleontologists are getting a glimpse at life over a billion years in the past based on chemical traces in ancient rocks and the genetics of living animals.
A new study of paper wasps suggests social interactions may make animals smarter. The research offers behavioral evidence of an evolutionary link between the ability to recognize individuals and social cooperation.
One of the most enduring questions of life is: How does it happen? One line of scientific inquiry lies in understanding gastrulation — the stage at which embryo cells develop from a single layer to a multidimensional structure. New research suggests that the same physical principles behind multicellular self-organization may have evolved across vertebrate species.
